Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 270-659-9 | CAS number: 68475-76-3 A complex combination of finely divided inorganic particles separated from the exit gases formed during the manufacture of Portland cement. The flue dust consists of uncalcined raw materials along with partially calcined materials. Some Portland cement clinker is usually included. The major constituents of kiln dust are calcium carbonate, clays, shales, quartz and sulfate salts. The following materials may also be present:@Dolomite@Ca(OH)2@Feldspars@CaSO4@Fly ash@KCl@Iron oxides@K2CO3@CaF2@K2SO4@CaO@Na2SO4@Glasses of SiO2, Al.s@Portland cement chemicals [659

Description of key information
Flue Dust: 0 - 175 µm, measured by laser granulometry
Respirable fraction: 10 %, calculated by SWeRF method
MMAD = 19.4 µm
GSD = 3.53
Additional information
The particle size distribution of the flue dust sample "Flue Dust T (REACH) was measured by laser granulometry (CILAS 1064). This measurement gives the particle size distribution in the range between 0.10 and 20000 µm.
The test item has a particle size range between 0 and 175 µm. The respirable fraction was calculated due to the SWeRF method.
Particle size distribution may vary, as Flue Dust is a UVC substance with a broad range in composition and constituents.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
